Subject [jira] [Commented] (HIVE-4641) Support post execution/fetch hook for HiveServer2
Date Wed, 05 Jun 2013 21:59:20 GMT


Carl Steinbach commented on HIVE-4641:

If the main use case is row-level security, then I think we're better off adding this functionality
in a way that makes the additional work visible to the optimizer, e.g. with views.

I think it would help to provide some more details about the motivation for this patch, possibly
including a concrete use-case as well. Thanks.

This can be used to filter results to enforce a specific security policy before returning
the result set to the client.
